What is an Investment ISA?
An individual savings account, or ISA, is a tax efficient wrapper that all UK residents can take advantage of. Each year every person in the UK has a certain allowance of how much they can put in to their ISA, and they will then not need to pay tax on any interest they earn (if a cash ISA) or any growth, dividends, interest or income (if an investment ISA).
There are currently the following different types of ISA available:
- Cash ISA
- Lifetime ISA
- Junior ISA
- Investment/stocks and shares ISA
What is the Investment ISA allowance 2023/2024?
For 2023/2024, the ISA allowance is £20,000. It is possible to split this allowance across different types of ISA. For example, you could put £5,000 into a cash ISA, and £15,000 into an investment ISA.
Are Investment ISAs safe?
An investment, or stocks and shares ISA, is by nature more risky than a cash ISA, as it involves investment. Any investment involves an element of risk, as your money is exposed to the markets, and the value of your investment can go up or down.
The different ISA providers are generally certain types of platform, and can potentially have different levels of risk. Robo-advisors, such as Nutmeg and Wealthify, are robo-advisors, and they are passive platforms, which means that they make the investment decisions for you. This should mean that they create a diversified investment plan which, in theory, should be safer.
How to choose an Investment ISA?
There is a very big range of investment ISA providers. In fact, most investment platforms will offer an investment ISA as part of their product range. Really, an investment ISA is just a tax efficient vehicle to invest. What you use to invest within that vehicle, and how you do it, is up to you. Therefore, the choice of an investment ISA will really come down to two things:
1 – How you wish to invest
Different investment platforms will have different ways for you to make your investments. If you want to be an active investor, and decide on which assets you put within your investment ISA, then you will need to go to a platform that allows that form of investment, such as an execution-only platform like Hargreaves Lansdown or Interactive Investor, or a trading app like Freetrade. Bear in mind that you will need to spend some time researching your investments!
If you would rather have a more passive investment experience, i.e. the platform you choose makes the investment decisions for you, then a robo-advisor such as Moneyfarm or Nutmeg, or automatic savings app like Moneybox (which acts in a similar way to a robo-advisor) would be better, as they will set up an investment plan for you, and you just let it run.
2 – Cost
The different types of platform will have different ways of charging for the investments and the ISA.
Robo-advisors will generally have a fee that is a percentage of the total amount you have invested, paid annually, which is usually between around 0.5% and 1%, depending on the amount you have invested.
Execution-only platforms will also have a similar fee, but it will tend to be lower than on a robo-advisor. However, on these platforms you have to make your own trades, and they will charge you for each trade you make.
Other platforms have hybrids of these charges, or completely different charging structures, such as Interactive Investor, who charge a monthly fee regardless of the amount you have invested, and Freetrade, which charge £3 per month for the ISA, and don’t charge for making trades.
To work out which one is best for you, it is best to look at the style of investment you wish to do i.e. active or passive, how many trades you wish to do each month (if any), and the amount you will have in your ISA, and this will allow you to calculate which one is the best one for you.
Best Investment ISA – FAQ
Is it better to have an ISA or a savings account?
In general, the main difference is that you will pay tax on any interest you earn with a normal savings account, whilst with an ISA, the interest is tax free. With an investment ISA, you would not have to pay tax on the dividends, or growth of your investments within the ISA.
Are stocks ISAs risky?
Investment ISAs always carry an element of risk, as any investment does. There is always the risk that you can lose money. It would generally be safer to put your money into a savings account via a cash ISA. However, the risk comes with the potential of reward, as interest rates have been low for a long time, and lower than inflation. With investment ISA, you do have the potential, if the investments are good, to make a bigger return.
